Plastic Magnetic Drive Centrifugal Pumps Available upon request: ATEX 100 Directive 2014/34/CE Flanges : UNI 1092 PN10RF type B ANSI 150RF STN 30 Compact, Plastic Magnetic drive Horizontal - Single Stage - Centrifugal pumps PP-GF (Polypropylene-Glass filled) - CFR - ETFE Close-coupled execution

The synchronous drive configuration STANDARD EXECUTION with motor is based on an outer magnet ring assembly built to magnetically couple The STN offer a wide range of materials for the wetted parts : • PP-GF (Polypropylene-Glass filled) • CFR-ETFE (Carbon filled - Ethylene tetrafluoroethylene) - *only with an inner magnet ring assembly. These two magnet rings are locked together by the flux of attracting magnet poles flowing through the containment isolation shell. Application fields ATEX EXECUTION without motor Suitable for handling corrosive, aggressive and hazardous liquids (low...

3D VIEW - STN 30 / 40 Inner and Outer magnets are equipped with rare earth permanent magnets. Patented cage magnet attachment guarantees stability during the operation of the pump. High chemical resistance employing a performing material as CFR-ETFE. Alternative available materials for the Wetted parts: PP. The casing’s design is reinforced by a solid rib structure. The STN are available in close coupled execution, suitable to be coupled with standard electrical motors. Sealless design. Total containment, essential for hazardous, aggressive or valuable product.

FEATURES - STN 30 / 40 CASING Available in CFR-ETFE and PP-GF execution. Standard casing drain for a complete and fast draining of the casing, IMPELLER ASSEMBLY • The integral design of the impeller and inner magnet prevents any misalignment problem, also reducing the production cost, • Standard back vanes reduce axial thrust and seal chamber pressures to guarantee an extraordinary bearing and seal life, IMPELLER ASSEMBLY • ETFE Non-metallic double Isolation Shell configuration on wet side, externally reinforced by a Polycarbonate can, As alternative, it is available made by a solid 3 mm...

3D VIEW - STN 70 Inner and Outer magnets are equipped with rare earth permanent magnets. Patented cage magnet attachment guarantees stability during the operation of the pump. The casing’s design is reinforced by a solid rib structure. Sealless design. Total containment, essential for hazardous, aggressive or valuable product. New internal circulation path to improve flushing and lubrication of bushes, to keep bushes and shaft cooled and lubricated, even under stress conditions, i.e. end of curve and/or cavitation conditions.

IMPELLER ASSEMBLY Available in PP-GF execution • Standard casing drain for a complete and fast draining of the casing. • The integral design of the impeller and inner magnet prevents any misalignment problem, also reducing the production cost. • Standard back vanes reduce axial thrust and seal chamber pressures to guarantee an extraordinary bearing and seal life. ISOLATION SHELL Available made by a solid 3 mm PP-GF layer Zero Eddy Current Losses thanks to non-metallic execution Axial and radial loads are well distributed thanks to the highly reliable rotating parts design. The static shaft...

The metal surfaces are protected by a high performance three layers coating (240 micron total) • Epoxy zinc paint • Epoxy amidic modified vinyl • Epoxy enamel paint or aliphatic acrylic polyurethane. • Available upon request : EN ISO 12944-5 C5M and C5I protecting paint system grades • RAL 1017
